ANATOMY AND FUNCTION OF THE HEART

The heart is a muscular organ a little larger than your fist weighing between 7 and 15 ounces (200 to 425 grams). It is responsible for pumping blood through the blood vessels by repeated, rhythmic contractions. The average heart beats 100,000 times per day pumping about 2,000 gallons (7,571 liters) of blood. The average human heart beating at 72 BPM (beats per minute), will beat approximately 2.5 billion times during a lifetime of 66 years.

The heart is usually situated in the middle of the thorax with the largest part of the heart slightly offset to the left underneath the breastbone or sternum and is surrounded by the lungs. The sac enclosing the heart is known as the pericardium.

anatomy of the human heart

The heart consists of the following parts:
Aorta: It is the largest artery and carries oxygenated blood from the heart to the rest of the body.
Superior Vena Cava: Deoxygenated blood from the upper parts of the body returns to the heart through the superior vena cava.
Inferior Vena Cava: Deoxygenated blood from the lower parts of the body returns to the heart through the inferior vena cava.
Pulmonary Veins: They carry oxygenated blood from the lungs back to the heart.
Pulmonary Arteries: They carry blood from the heart to the lungs to pick up oxygen.
Right Atrium: It collects deoxygenated blood returning from the body (through the vena cavas) and then forces it into the right ventricle through the tricuspid valve.
Right Ventricle: It collects deoxygenated blood from the right atrium and then forces it into the lungs through the pulmonary valve.
Left Atrium: It collects oxygenated blood returning from the lungs and then forces it into the left ventricle through the mitral valve.
Left Ventricle: It is the largest and the strongest chamber in the heart. It pushes blood through the aortic valve and into the body.

HOW DOES THE HEART FUNCTION?

The right side of the heart collects de-oxygenated blood from the body into the right atrium and then via the right ventricle pumps it into the lungs so that carbon dioxide can be dropped off and oxygen picked up.

The left side of the heart collects oxygenated blood from the lungs into the left atrium. From the left atrium the blood moves to the left ventricle which pumps it out to supply oxygen to the body.

Surgeon on Robotic Console

Robotic System-daVinci Telemanipulation Robotic Cardiac Surgery is performed with the help of da Vinci telemanipulation system (Intutive Surgical, Inc, Mountain View, California, USA). The da Vinci system is computer enhanced system that consists of surgeon’s console and cart mounted manipulators.

 

Such endoscopic surgery works well for several types of operations (such as gall bladder removal and knee repairs) where part of the body to be operated upon motionless and surgical maneuvers to be performed are relatively simple. Thus endoscopic surgery has achieved only limited success in more complicated operations such as heart surgery, where the heart is beating and the necessary surgical maneuvers are complex.

 

The console houses the display system showing three dimensional pictures of the patient’s chest cavity, the surgeon sits away from the patient at the console and gets the view of inside of the patient’s chest cavity. The manipulators hold the tiny instrumentswhich go inside the patient’s chest. Surgeon’s hand movements are transmitted to these instruments facilitate different cardiac operations. Coronary artery bypass grafting (CABG), mitral valve repairs and closure of atrial septal defects have been performed successfully through this technique.

IMA – LAD Anastomosis with Robotic Instruments

T-CAB (Totally Endoscopic Coronary Artery Bypass) T-CAB is performing Coronary artery Bypass totally endoscopically without opening the chest at all. T-CAB is performed with the help of computer assisted robotic technology(da Vinci telemanipulation system). The robot is not autonomous. On the robotic console surgeon’s hand motions are captured, transformed and then transmitted to tiny instruments inside the chest cavity to perform complicated cardiac procedures. The surgeon’s had movements are transmitted to tiny instruments that facilitate and endoscopic anastomosis. The control is so perfect that cardiac surgeons are able to construct an anastomosis in the customary fashion without placing a hand inside the chest cavity. The surgeon sits at a console, peering into the chest with 3-dimensional vision and working with perfection. This technique has great cosmetic advantage as there are only 3-incisions, each only 1 cm in diameter on the side and lower part of chest instead of long cut in the front of the conventional surgery. A smaller incision (cut) also means less pain, faster healing and recovery and short hospital stay.
